The AquaHot installation manual says it can draw as much as 15.33 amps. Each heat exchanger, while actually delivering heat, draws about 2 amps. Also, each zone pump, while actually delivering heat, draws about 2 amps. The diesel burner draws about 5 amps, while burning.
Your Dynasty most likely has at least a 400 amp-hour battery, and based upon the above, you can expect a load of roughly 4 amps per zone, while actually delivering heat to the zone and roughly 5 amps to the burner, while it is actually burning. I don't know where the 15 amp number on the nameplate comes from, unless the 5 amp figure that they cite for the burner doesn't include the ignitor and the fuel pump. But even delivering significant heat, the burner only runs about seven or eight minutes, occasionally, to keep the reservoir hot. If your batteries are healthy, you should be fine for a night or two.
These AquaHots are truly an awesome way to heat a coach, and deliver domestic water at the same time.
One thing you should note. Your front zone requires the fan under the kitchen counter to be manually set to run on low, medium or high speed, and it runs all the time, whether delivering heat or not. It's a bit much for this response to include the detailed how of it, but we had Monaco put a relay in the ground circuit for that fan module and control it from the zone pump connection on the AquaHot so that the fan only runs when the zone is actually calling for heat.
